Hy when i click right mouse click on anything, nothing happens. How do I enable both left and right mouse click ??? The mouse works on a different computer.

Have you checked in the control panel>mouse and checked what the settings are?
What about: 1) Mouse driver (maybe it needs any special one)
2) Virus. Check your computer. You may also do it here:
For if you do not have right click in the Start Menu-- Right click Start button,
then Properties,
then Customize... button,
then Advanced tab,
in the Start Menu items list, check mark
"Enable Dragging and Dropping".
